Invalid dimension/metric/data source problem continues

This problem has persisted for about a month now, with no news of a fix in sight. It would be nice to get some kind of a response from someone at Google about these issues.

I created a new report just this morning, as my organization is working towards a website redesign, and I wanted to gather together the most pertinent information and present it cleanly in Data Studio. Not to be, as already I'm getting the invalid dimension/metrics errors in the report.

Also, it's no good to try to get a report from our Analytics account as I can't email or export a report to myself because of an error there.

So I'm left not being able to do anything, and with no response from Google I can't explain to my boss what kind of solution to expect.

How can charts now show "invalid dimensions and metrics" (dimensions and metrics that were fine yesterday), and show that the data source needs to be added (it was added to the report at the beginning) be user error?
